Homicide Suspect Apprehended

October 22, 2018

In the early morning of October 21, 2018 18-year-old Joseph Caballero and 30-year-old Matthew Vacaneri arrived at the residence located at 801 N. Dakota St. with two females. Joseph and Matthew brought the females to the residence with the intent to sell their services for the evening to 29-year-old German Roman Medina. During the transaction, an argument broke out over the price German was charged for the females. The argument then escalated into a physical altercation.

During the fight, Joseph brandished a handgun and allegedly pointed it at German. Matthew grabbed the gun from Joseph and, after firing one round in the air, allegedly fired at German, striking him in the chest. After German was shot, Joseph and Matthew fled the scene in a vehicle with the two females.

German was transported to a local hospital and pronounced deceased.

With assistance from the U.S. Marshal’s Office, Tempe Police Department, and the Mesa Police Department, detectives from the Department’s Criminal Apprehension Unit arrested Joseph in San Tan Valley around 5:30pm. Matthew was apprehended later that evening in Chandler. Joseph and Matthew were both booked into the Maricopa County Jail on one count of Aggravated Assault and 1st Degree Murder, respectively.
